the load receiver has been dependent upon the operation of To all whom, it may concern: J

arts resting upon the scale- Be it known that we, Gnonun F. 'luumcn, a resident of Brooklyn, Kings county, and CHARLES E. Valid, a resident of York, county of New York, State of New York, citizens of the United States, have invented certain new and useful Improvements Automatic VVeighing-Machincs. of which the the poisiug movement of such beam. In the present construction these factors which tend to impair the accuracy of the weighing operation have been materially reduced. One of thc princi al means for accomplishing this l following is a specification. i result is t 10 mechanism employed for sup- This invention relates to automatic u'eiglc porting the load-receiver, an another is the inganachines of that class adapted for weighmechanical isolation of the stream-controller ing predetermined loads; and the principal f or cutotl valve from the beam mechanism objects of the invention are to reduce to a 1 during the completion ofc load. .minimum those factors which ordinarily iu|- i "lhepriucipsl feetureof the weighing mechpuir the accuracy of the weighing operation i and to reduce the time required by the mcchanism for making up and poising the prcdetermined load. In weighiug-umchines ot' this type as hcretot'ore constructed it lies been custonutry to feed to a load-receiver or bucket first it main stream for making up somcwlntt rapidly the major portion of the load and afterward adrip-stremu iorsupplyiug more slowly the small amount required i movement rchitivc to that of the main scalefor bringing the total load to a poise, in one i imam for poising the whole load supplied to type of such machines holh the main stream the lozuhrccciver. The main SCttlPrbGflJl'l and and the drip-strewn have been lorl from n lln.-:ii. ;ilim'y scale-beam are so counterpoised single source or spout and have been con as to permit both beams and the load-re trolled by one or moriill!\i('i$, 'llt'li icy-sir s. cciver to more in unison during the last mot'or reg-u sting the lion in another type ments of the delivery of the main stream for the main stream has been drlivercd from one i ihc purpose of pulsing the main supply; but source or spout and the drip-strrwim from alter the main supply has been poised the another. in both however, th Hl'IH't-HH'HX l mom ntumolthcmainscalc-bcumischeckcd. ofasinglc couuicrpoiscd scab-dream hasrom Y ulnl it preferably has no urther movetrolled the shutting oil' of the main sin-inn went, but is locked in, its ioiscd position, and the drip-stream. and in both the loadwhich is substantially the horizontal, and receiver has been mounted upon :2 scelcihcpoisiugoi the totalload,1unldc by adding beam having it cm'isidcrablc range of movcto the main supply a suitable drip-supply, is mcntduring the delivery of the load and the cil'ec-ied by a cmnperetively small poising weight and momentum of the load and the movement of the auxiliary scale-beam rclaimpact of the material hilliup thereon have i live to the mainbcmn, which movement is anism proper which distinguishes the present wcighingmachine from those heretofore used is the employment of a air of counterpoised scale-beams, one of w ich constitutes the main scale-beam and is pivoted on a suitable support, while the other. which is herein termed the auxiliary scale-beam, is pivoted on the poising side of the main scalehcam, supports the loed-rcceiver, and has a all been exerted upon the team and trnnspreferablyfromahorizontal position. These mittcdv thereto throughout the entire period poisiug movements of the main sceleducem of delivery of the load up to the moment of and the auxiliary scalc-beam are utilized in cut-off of the (lI'l])-StI0tHH. in all of these this construction to control, respectively, the scales, so fares wcarca are, tlicscalc-lieem cutting off of the main supply and of the has been brought to o horizontal or poising I drip-supply, the latter of these functions position by the drip-supply and eonsidcricing preferably governed electrically in able time has been r,- lured to bring; the. order that the auxiliary scele-bcam may be scale-beam to this position and carry it bcentirely clear of the strewn-controllingmeans yond the at the moment of pulsing of the total load.

ant feature of this invention is an nnproved type of strewn-controlling means for permitting the rapid delivery of the drip-strcam supplied to the load-rccciver. In mostof these machines. also, the reduction poising-linc, owing to the small size i Anothcrunporl l l or cut-off of the stream supplied to beam and deriving their movements fromand effecting the rapid cut-oif of tlie stream of material delivered to the load receiver. We have found that a stream-eontroller or cut/411T device may be made to operate posi- 5 tively and rapidly if it is permitted to gravitate in the direction of the flow of the stream for effecting the cut-off of the same, and the best results have been obtained by employil'ig stream supplying and cont rolling means [0 having coacting cut-otl' faces one of which forms a hollow su )ply-stream and is prefer ably circular. The preferred means emplo ed for this purpose are a sup )ly-spout and a coacting tubular cut-oll' member which moves relatively thereto and forms therewith a supply-stream which is hollow and is delivered evenly to the loiul-receiver at all points in a path corresponding to the outline of the'hollow supplystream. A single tnliu- 2o lar cut ofl member is preferably employed I for delivering and cutting off both a main stream and a drip-stream, and the two cutoff movements thereof are controlled in this case by the main scale-beaiii and the auxiliarv scale-beam, respectively.

load-receiver is synchronous with the deliv cry of a drip-stream to another load receivi-ig and this IS the type of machine illustrated as embodying our invention in the accompanyigure 1 is a front elevation of such a die plex automatic \\"(l;;flllligf-dilfttliitu, showing the positions of the :it! being (lCllYti'ttl iii (ltilt't ilitithltt il'tl'.

Similar characters designate like parts in all the figures of the drawings.

Any suitable means ma be employed for 0 supporting the several opcratiye parts of the duplex automatic wcighingqiiachine illustrated in the accompanying drawings. 'lhat shown embodies as its principal elements supports or legs 1, which at their upper ends have secured thereto a pair of side frames '2. From the centers of the side frames 2 rise short standards or posts 3. Suitable end pieces or cross-bars 4 and center pieces or cross-bars 5 and 6 are employed for connect ing and stiffening the side frames 2 and for supporting various operating parts of the mechanism. Between the side! frames 2 the scale-beams and load-receivers of each weighing mechanism of the duplex automatic weighing-machine shown are mounted for operation. As the different elements of the second weighin mechanism are preferably and sis-shown ierein identical in construction with corresponding elements of the first weighing mechanism, only one of such mechanisms will be described in detail, and the corresponding parts of the other will be designated by similar reference characters. The main counterpoised sca'lebeam of each weighing mechanism will preferably be of the counterweighted type, and this main scalebeam is desl nated 5. It may be supported in the wellnown manner by knife-edger pivots 6, restin on V-sliaped bearings '2. lhis beam is ire 'erably forked at its poising side and, as shown (sce'Fig. 5,) this fork extends to the counterpoising side thereof, and the main central portion of the scalebeam at the couiiterpoising side of the beam carries a counterweight S, corresponding to the weight of the main supply to be delivered to the load-receiver for making up the predetermined load. This weight is or may be ad just-able in position on the main SCttlCl)(t1lli and is held thereto inthis construction by means of a screw-bolt 9. Within the forked portion of the main scalc-hcani an auxiliary scale-beam may be mounted so as to move normally with the main scale-beam but haw iiig a relative movement thereon for the purpose of poisiiig the total load after the drip supply has been delivered to the load-receiver. 'lhis auxiliary scalcbeam is designated generally by it] and is also preferably forked at its poising side, the forked portion of this beam also extending in the construction shown to the counter ioising side thereof and the main or central arm of said auxiliary scale-beam also having secured thereto a counterweight, such as ll. The masses of the counterwcights 8 and ii and the leverages of the beams by which they are carried are such that the weight 8 will poise the main supply, which may be, say, seven-eighths of the total load, while the counterweight It will poise the total load. Xiii'iiially the anxiliary scale-beam is supported on and moves with the main scale-beam, the outer end of the counterweight ll resting in this construettion on a stop 1'. on th main scale-Imam.

The auxiliary scale-heam' also has knifeedged pivots 13, similar to those of the main scale-beam and resting on V-shoped bearings 14, corresponding to the bearings 7 on the side frames. By means of these devices the auxiliary scale-beam is pivoted on the I ois irtg side of the main scale-beam nt the desired distance from the axis of movement of the main scale-beam. 'lhe loail-n-reiver or bucket for holding the load to be weighed may be of any suitable type, but will preferably be a bucket the bottom of which has a swinging closer. Such a hind-receiver is shown herein and is designated 15, its closer being designated by 16. This load-receiver has at opposite sides thereof and near its upper ends the usual V-shnped bearings 17, which rest on knife-edged pivots 18, carried by the auxiliary scale-beam at a suitable distanee from the axis of moven'ient of said auxiliarv scale-beam.

T e normal position of the auxiliary scalebeam with respect to its main scale-beam as determined by the stop 12 has been herein before mentioned. The movement of said auxiliary scale-beam relative to its main scale-beam will usually be comparativelvsmall, and e sto S on the main weight 5, defines the limito its poisingmovement. The movements of the. main scale-beam also will both be limited bysuitnble stops, one of which is referahly a fixed stop such as it), adjustabl as required, this stop being adapted to determine the limit of the poising movement of the main senledueain. The other limit of movement of the main scalebetun-to wit, the limit of its movement when in its counterpoised positiou will preferably be determined by a shillable stop, such as that shown at 20. this stop in the present construction being :orried by a swmging arm 21, pivoted on the ('IQSNlNLI 4 and suitably weighted utns lower end for y the Jur lose of nornnlllv holding it in iosit ion to enah e the main scale-Mam to ri-st on one i llumtlol' of two stop-faces carried thcrel v. of these stop-faces is shown at 22 and roost itutes an element of llltlfllci for latching r looking the main sceledwam in its poised pit-- sition against. the stop It), in which position said 11min si'wule-benm is supported by the framework and cannotmove in :1 ydireetion. By referring to Fig. 2 it will be seen that the main scale-beam is locked in this position after the load-receiver carried thereby has received its main supply, and when so lock d the iactor'of momentum, which is present in all Weighing-nmehines in which. the sci-ilebeam descends continuously through a considerable arc of movement alter the poising movement has begun, disappears so for its saidmein scale-beam is concerned.

The devices for holding the bucket-closer 16 in its locked position and for releasing the same are or may be substantially similar to other devices employed for the same purpose. Here the closer to is pivoted at the outside of the bottom of the bucket and has a counter weight 23 extending beyond said pivot for the purpose of returning the closer to its shut position after it has been opened and the contents of the load-receiver discharged. At its inner free end said closer 16 has a stop 24, adapted to be engaged by a latch 25, )ivoted near the inner lower end of the hue at and normally held in engagement with said stop by means of a spring 26. At its upper end the latch 25 of the holding means for the closer is so constructed as to cooperate with and he releasable hysuitable releasingortrip ping means, which will he hereinafter described. Thecloser 16 will also referahly control the return of the main seat e-bealn to itsnormal position and through it the delivery to its load-receiver of the main supply in a manner which will he hereinafter described, the release of the main scale-beam from the stop-face 22 of the hitch 21 being effected in this construction by means of a resilient tapper, such as 27, secured to the extended outer portion of the closer 16 and in a position to onset with the lower end of said latch and release it from the main scale-beam when the closer is returned to its normal position by the counterweight 23.

Suitable streinn-controlling means will be employed for delivering a main stream to the load-receiver during the first part of the weighing operation, and thereby making up the main supply in said receiver, and for afterward delivering a drip-stream to said loi'nhreceiver and making up the drip-supply l l l l i l l r l rei uirl-d to complete the loud. The delivery of these main and drip supplies will be suit- :ihlv governed by movements of various opernting parts, the shut-oil of the main stream and afterward of the drip-stream delivered to the loml-receiver being governed by the difl't-renl ial poising movements hereinhefore de- M'i'llHJtl" viz., the poising movement of the main Slittltdlt'tllll to the position in which it is locked to the l rinnmvorlc and the poising movement of the auxiliary scale-beam about its pivot on and relative to the main sealehenni nttersurh main hezun has been locked to the lrnnn-worh. This poisiiig movement of the main beam is ordinarily much greater than the subsequent poisiugmovement oi the :inxilinrv scale-beam relative thereto. In order. however. that the relatively slight movement which the :mxilinrv scale-beam will have at its point of support for the load ply to said lomlwmrr-ivermuyrontrol with precision the point oleut-oll ol the drip-stream, we prefer to make use of a controlling device having a multi ilied mo'vement witlr respect to that ol' the load-receiver for the 1m )ose of determining the moment of cut-oi o the drip-stream. 'lhiscontrolling device will also pref iblv be out irol eloui'oi t host rozimcontroller proper or valve by m ans oi which the size. or the supply-openiug is dirt-oil rot ulated and is here shown a an elect rioal roni tact device, the contact portion ol' which is 1 carried at such :1 point on the auxiliary scale t beam as to have a iui'ivoinenl several times l that of the pivot of support oi the loadu'oceiver. Here the poising end ol' tho auxiliary scale-beam has extending therefrom an arm 28, nti tho free end of which :1 pair of electrically-conneeted metallic contacts 2.), insulated from the arm 28. These contacts cooperate with n'couiplelm'nt any contact (le vice, which in this case consists of a pair of mercury-cups 30. carried by a suitable insulnting-blockfl I mounted on the eross pieee t5. lhe relativelvslight movement of the auxiliary senledieam about its pivot 15% while the main beam is in the position shown at the left in Fig. 2 is so multiplied at the contacts 2!) as to assure the out-oil of the drip-stream at the exact point desired. The relative poi itions of the contacts may oloourso b adjusted properl to obtain the desired results. Owing to the fact that the main scale-beam 5 controls the delivery of and is go\ ornod by the main suppl only and does not govern and is not. controllod by tho total load. it is not necessary to isolate the stro: u'| ontrolling means and the main soalo-lioain uioehanienlly during the delivery or at the moment of cut-off of the main stream. llonoo no lu'n'o shown herein nioausoarriod by the main soalw beam for governing the delivery and oul-olloithe main stream. the moans shown being: a rein-arm J53, t'tll't l cooperating with a stream ronii-oli' weight of which is noz'uiall h mo main sonledi aiu, is usioinai z 1i Inatic weighing-ninthinos n \(lll 'll the who IHUVQIYIPUtS'l rHgtiVt'I'Hilig both ziio :rlii supply and the drip-supply are regulated in :1 single st'nle-bemu.

stream-controller or collar is operative for first permitting, then shutting oil, and alter ward partially restoring the llow of the stream of material to its load-receiver. The particular construction of the means for accomplishing these results is not essential; but the devices herein illustrated have hccn found to work well in practice. The principal element of this part of the SiICtllll-t'(Hl trolling means is a lever 41, which is pivoted near its center in the uprights 3 and adapted 'fo operate in a manner similar to a walkingoq-am, the two ends of this lever being forked, as shown clearly in Fig. (i, and lying helow the pins 35, extending from the collars 34, The movements of this lever 41 are here controlled by a air of elcctromagnets 42, each of which in t is construction is of the duplex The armatures of these two electro magnets are shown at 43 and are carried by the lever 41, and said lever is oscillated first in one direction and then in the other on the cnergization of the corresponding magnet, The circuit of each of these magnets is a very simple one and contains only a single break adapted to he closed by the contacts?) and 30. When the contacts 29 (shown at the left in Fig. 7) dip into their corresponding mercury-cups 30, a circuit is closed from a source of energy such as hatterv 44, through i a conductor 45, contacts 3H and 20, conductor 46, and the magnet 42 most Hillulrthcrcl'rom. W'hcn the other pair ol contacts 2U dip into the other ltl(5[(fUI' \-t't!; ill, the circuit is the same from the hattcry to the cups 30, from which it passes by way of conductor 47 to the other magnet 42 .\lcan.s. such as the spring arms or latches an. arc also provided lot latching the lcvcr 4! in its respective positions, lhcso springarms tiring); curvcd at thcir lower ends and adaptcd to cxcrt considcrahlipressure against llio inncr l'accs ol the yoltcs when adjaccnt icrcto, 'lhis spring-prcssurc will he sullicicnt to hold the lever lirmly in its latchcd position cvcn \vhcn thc pins on the collar 34 are rcsl in; on one of the yokes and said collar thus sup- )ortcd hy the lover.

The releasing or tripping device shown is a stop 49, projecting rcarwardly from the lower end of the long arm of an angle-lever 50, pivoted upon a depending arm 51 of the framework, the short arm of this angle'lever living joined in this case by a connecting-rod 52 to the lever 11 at a point at the opposite side of the vertical line connecting the pivots ol said levers 4i and 50.

These studs and the buckets are also joined by suitable connecting means for preventing undue swinging or swaying movements of the bucket during the weighing operation, the means shown being connecting-links :35, having at their ends V- shaped hearings coacting with knife-edge pivots on the buckets and said posts, respectively, for the nirpose ol' reducing friction at these points ol connection This hopper 53 serves in a welhknown manner to delay slightly the return of each closer to its normal position and to render such return impossihlc unlt-ss the hopper is empty.

"l ltc operation ol' a du )lex automatic wi-ighiugiuacliinc adapter for weighing Pll'llti(llllllltll loads and illustrating one cinhodimcnt oi the invention disclosed in this application is as follows: Assuming that the parts are in their normal positions (shown in Fig. 1) a stream of material will he permitted to llow through the suppl v-s unit and its branches 3&3. 'lhc llow of this stream will usually he cut oil by means of a sliding gate (not shown) located at some point in the supply-spout above the collar 34. The stream thus turned on will [low into the left-hand huckct until the delivery ol the main supply is colnplctcd, h v which time the main scalehcam at the lclt will have moved to the limit of its poising swing and will have been locked against the stop 1!) by the latch-face 22 of tho incmhcr ll, the weight of the lower end of this member being sullicicnt toshil'tit un- (l('[ lhc outt'r end of said main beam the molnclit said hcam rides above the connecting l'aco hotwccn thc stops 2H and .21 During this time the main supplyis being delivcl'cd to the other lo.-td-rocciver at the right'hand side of the machine; but as soon :is its main supply is completed the flow of material to the right-hand bucket will be completely shut oll', owim to the fact that the righthand end of the lever 41 is down, and the right-hand collar 34 may descend with the coactin Y cam 32 and main scale-bcuu1 to its shut-o1 position. The left-hand end of the lever 41 is, however, elevated, and hence the left-hand collar 34 can descend only to its partial open or drip-supplyin position, (see Fig. 2,) in which position it will-be supported by the pins 35, resting on the arms of the yoke atlthe left-hand end of the lever -11v The dri i-stream will continue to be delivered to the left-hand bucket until the weight of the main supply, plus that of the drip-supply, poises the left-hand auxiliary scale-beam, when said auxiliary beam will move relatively to its main beam, and its load-receiver will descend again and move a short distance farther, when the left-hand contacts 2!] will dip into the mercury-cups 30 and a circuit will be instantly closed through the right hand magnet 42, whercu on the lever 41 will be instantly shifted to t to opposite position (shown in Fig. 3) and latched therein, the left-hand collar 34 dro ping as the lever is shifted and instantly shuttmgofi' the dripstream. At the same time the right'hand collar is elevated by the right-hand yoke of the lever ,41 to its partially-open or (hipupplyin position, as shown at the right in Fig.

3, and the drip-supply of the second loadnw ceivcr begins to llow into said receiver. At the same time also that the lever 41 is shifted the connections between it and the releasing device 49 shift this releasing device into the path of the upper end of the-latch 25, which is instantly tripped and the closer opened by the weight of the load. The moment the lelt-hand load-receiver begins to disi'hangc its contents, as shown in Fig. 3, its auxiliary scalebcam returns to its normal horizontal counter oised position, and its contacts 29 are wit idrawn from the mercury-cups 31]. The main scale-beam, however, remains locked in its horizontal position until the contents of the first bucket are dischar cd therw from and are nearl "discharged out the hopper 53, whereupon the counterweight 2.;

becomes cilective to return the closer to its normal shut position, in which it will be fastened again by the latch 25 and the stop 24. Just after the closer is latched shut, howcycr, the resilient tapper 27 strikes the lower end of the arm 21 a hard blow and knocks the latch 22 away from the left-hand main beam, whereupon said beam returns to its normalposition and its cam 32 raises its collar 34 agaiin'and the delivery of the main supplv begins again for the makingot a new load. As soon as such main supply is made up in the left-hand bucket the sup )lv will be coin- Pletely shut off. because the left-hand end of the lever 41 will not then he in a position to support said collar, and the collar will move with its cam, to the limit of its downwar movement.
